Taparithmetic

Rules:Follow regular tapa rules.Additionally,sums of numbers in shaded cells are equal across identical outlined regions.

Superimposed tapas

Rules: Two (imagine the paper is transparent) tapas with digital clue digits were exactly overlapped on one another.Some clues are on the same cell in both grids.Some clues are in different cells.If both puzzles have a clue in the same location,those clue will be identical with respect to the number of digits.Zeros are not allowed. Separate the two grids,determine the correct individual clues and solve both puzzles

Anti-knight tapa

Circular growth

This is one of my latest inventions.
Shade some cells in a circular way starting from each clue,by choosing one of the upto eight neighbouring cells as the centre of the circle,and moving either clockwise or anti-clockwise, until that many cells are shaded,such that all shaded cells are orthogonally connected in the end.2x2 squares of all shaded cells are not allowed.Every clue should have exactly one circular growth.Circular growths from different clues often overlap.In the end, every shaded cell should belong to atleast one circular growth.

Tapa:Two or less

Rules:Paint some cells black or grey,to create a continuous wall.Number/s in a cell indicate the length of black cell blocks on its neighbouring cells.If there is more than one number in a cell,there must be atleast one white cell between the black cell blocks.Painted cells cannot form a 2x2 square or larger.There are no wall segments on cells containing numbers.
Shaded cells around the clues cannot have more than two shaded edge-adjacent cells.

Yajiline

This is a new yajilin variation in line with my past ideas based on segment lengths.But i didnt apply these ideas on yajilin,before seeing this.
Puzzle modified for uniqueness

Rules:Shade some cells following the clues.Adjacent cells cannot both be shaded.Then draw a single closed loop through all the unshaded cells.The numbers are either the number of shaded cells in the direction of the arrow, or the length of the longest segment in that direction.Sometimes,though not on purpose,the clues might indicate both quantities.

Thermosnake

Rules: Shade some cells to form a snake that does not touch itself,even diagonally.The thermometers must be filled starting in the bulb.Head and tail of the snake are given as black dots.Numbers outside indicate how many cells are shaded in that direction.

Tapa turns

This is a tapa turns.
Puzzle edited in the right middle for uniqueness.

Liar calcudoku

This is one of my calcudoku variations.

Rules: Place a digit from 1 to 6 in each cell such that every row and column contains each different digit exactly once.Numbers inside every cage indicate the results of mathematical operations applied on all the digits inside the cage.Every clue is false.It is either one larger or one smaller than the actual values.Determining which operation is used is part of the solve.Subtraction and division work on two digits only.

The colors of tapa

Rules:Paint some cells black or grey,to create a continuous wall.Number/s in a cell indicate the length of black cell blocks on its neighbouring cells.If there is more than one number in a cell,there must be atleast one white cell between the black cell blocks.Painted cells cannot form a 2x2 square or larger.There are no wall segments on cells containing numbers. Numbers are either black or grey.The corresponding shaded cells should be the same color as the clue number is.All shaded cells of one color should be reachable from each other without visiting a cell of the other color enroute.

Tapa: Complementary pairs

Rules:Paint some cells black to create a continuous wall.Number/s in a cell indicate the length of black cell blocks on its neighbouring cells.If there is more than one number in a cell,there must be atleast one white cell between the black cell blocks.Painted cells cannot form a 2x2 square or larger.There are no wall segments on cells containing numbers.
Identical cells in every pair of identical outlined regions must one be shaded and the other unshaded.All such pairs of outlined shapes are asymmetrical.
If, for example ,the corner cell of an "L" tetromino is shaded ,then the same cell in the other "L" tetromino must be empty.This applies to all cells of the shape.

Kakuro-style tapa

Rules:Paint some cells black to create a continuous wall.Number/s in a cell indicate the length of black cell blocks on its neighbouring cells.If there is more than one number in a cell,there must be atleast one white cell between the black cell blocks.Painted cells cannot form a 2x2 square or larger.There are no wall segments on cells containing numbers.
Clues in black cells indicate the number of rows of uninterrupted shaded cells in that direction.Every such set of rows should be of different lengths.If a clue contains the number '2' for example,two shaded blocks of different lengths should appear in the correspoding direction.

Design contest 2: Update

I have too few submissions to close the contest.I am extending the deadline to the 9th of september.
